My parents have an old Compaq Presario SR1950NX that works perfectly fine, but hasn’t been used in at least 15 years. Obviously I can’t connect it to the internet with Windows XP, but before I recycle it I thought I’d see if anyone had any cool ideas for how I could use it. I’m sure I could find Linux distro that would work, but I don’t really need another desktop PC in the house.
If I’m looking at the board correctly, you can install 4 1gb DDR memory sticks and 4 SATA drives. It will be a bit pokey, but I envision a TrueNAS with 1 SSD and 3 2 TB+ spinning drives set as ZFS RAID-Z1. Rip all your DVDs and use jellyfin to watch them.
